A machine used to fill gallon-sized paint cans is regulated so that the amount of paint dispensed has a mean of 127 ounces and a standard deviation of 0.40 ounce.
You randomly select 40 cans and carefully measure the contents. The sample mean of the cans is 126.9 ounces. Does the machine need to be reset? Explain your
reasoning

Which of the following contains a variable?

|y + 2| > 6 {y|y < -8 or y > 4} {y|y < -6 or y > 6} {y|y < -4 or y > 4}

Astudent solves the equation for v. start with the original equation. use the square root property. use the division property of equality. use the multiplication property of equality. simplify. which statement explains how to correct the error that was made? the square root property must be applied after all other properties of equality are applied. the multiplication property of equality should have been applied before the division property of equality. the division property of equality should have been applied to move the fraction to the other side of the equation. the square root property should have been applied to both complete sides of the equation instead of to select variables.
